The characteristic plants of this rock, as seen at Kifhauser and Eisenach, aw 
silicified Psaronites. The uppermost beds of the Rothe-todte, of a greyish ami light 
colour (“grau liegende ” and “ weiss liegende are exposed in natural sections on 
the N.E. flank of the Thuringerwald, where they are surmouutcd by bituminous 
schists and the Kupfer Schiefer with its fossil fishes. 
The Zechstein offers in its details nil those mineral and zoological distinction* 
which have been pointed ont in the works of Sedgwick and King, tbc one on the 
Magnesian Limestone, the other on the Permian fossils of England; the principal 
distinction in Germany consisting of enormous interpolated masses of gypsum. Sir 
Roderick then explained why, in proposing the word Permian, be had further in¬ 
cluded in this group a certain portion of schistose and partly calcareous red rocks 
which everywhere overlie the Zechstein or Magnesian limestone, and often con- 
stitute ridges separated from the “ Bunter Sandstein,” properly so called, or base of 
tho Trias. In this way lie considered the Permian (which in Russia, whence b# 
derived the name, lias mottled copper sandstones with plants and conglomerate' f»r 
above the Zechstein) to ho an under Trias; the Zechutoin limestone being placed 
between two red formations. 
1 hough only indirectly connected with the object of this communication, the 
tabular view exhibited the chief divisions of the true German Tria* or base °f *' 
secondary rocks with its profusion of largo Saurians ; attention being specially calW 
to the entire change of animal life in passing from tho Permian or uppermost 11 
zoic into this lowest Mesozoic or secondary rock, though tho one was perfectly con¬ 
formable to the other: in other words, he demonstrated how, in the long lapse 0 
time, the primeval creatures had dwindled away and finally expired, to be succco c< 
by entirely new creations. .
